 ## Required Libraries
 
 Before you can use the project to write GPU crates, you will need a couple of prerequisites:
-- [The CUDA SDK](https://developer.nvidia.com/cuda-downloads), version `11.2` or higher (and the appropriate driver - [see cuda release notes](https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html)) . This is only for building
